Here is a little project I did for my friend Mike. Mike and I work together at Nvidia. Mike built this nifty little media PC using the small and cheap ZOTAC IONITX motherboard. He got a bare aluminum box and ask me to help him jazz it up with custom shinny black acrylic panels for the sides and front. The front pannel includes cut-outs for the optical drive and power button and lights, and an engraved Nvidia ION logo. Its a nifty little maching that can do very impressive computation at low power. I think Mike did a great job of making a stylish PC.
